豐富的推送通知在 iOS 中的 iPhone 11 Pro Max 中不起作用

Question

我正在嘗試在推送通知警報上顯示圖像。 這適用於 iPhone X、iPhone XR、iPhone 7 等其他設備。但不幸的是，這不適用於 iPhone 11 Pro Max。 我的客戶有 iPhone 11 Pro Max，因此我無法調試問題。

我從推送通知有效負載中獲取代碼並從該代碼下載圖像。

我創建了“通知服務擴展”的擴展

 {
self.contentHandler = contentHandler;
self.bestAttemptContent = [request.content mutableCopy];

NSString *alertText = self.bestAttemptContent.body;
NSString *stickerMessage = nil;

if (arr.count > 1){
            //Check if text is of sticker
            if ([self isStickerMessage:arr[1]]) {
                alertText = [NSString stringWithFormat:@"%@:",arr[0]];
                stickerMessage = arr[1];
            }
    }

// check for media attachment, example here uses custom payload keys mediaUrl and mediaType
if (stickerMessage == nil)

    [self contentComplete];
    return;
}

Answer 1

我不確定是什么問題，但我直接從 URL 下載了圖像，而不是使用 NSURLSessionDataTask & 這解決了問題。

以下是我寫的代碼

- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent *_Nonnull))contentHandler
{
self.contentHandler = contentHandler;
self.bestAttemptContent = [request.content mutableCopy];

NSArray *arr = [self.bestAttemptContent.body componentsSeparatedByString:@": "];
NSString *alertText = self.bestAttemptContent.body;
NSString *stickerMessage = nil;

if (arr.count > 1){
    //Check if text is of sticker
    if ([self isStickerMessage:arr[1]]) {
        alertText = [NSString stringWithFormat:@"%@:",arr[0]];
        stickerMessage = arr[1];
    }
}

// check for media attachment, example here uses custom payload keys mediaUrl and mediaType
if (stickerMessage == nil)
{
    [self contentComplete];
    return;
}

NSCharacterSet* characterSet = [NSCharacterSet characterSetWithCharactersInString: @"[]"];
NSString* stickerName = [stickerMessage stringByTrimmingCharactersInSet: characterSet];

if (stickerName)
{
    NSFileManager *fileManger = [NSFileManager defaultManager];

    NSURL *documentsDirectory = [[fileManger URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] firstObject];//FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
    NSString *fileName = [NSString stringWithFormat:@"%@.png",stickerName];

    NSURL *fileURL = [documentsDirectory URLByAppendingPathComponent:fileName];



    self.bestAttemptContent.body = alertText;
    NSString *picURL = [NSString stringWithFormat:@"https://stickerpipe.com/stk/emojiabc/%@_hdpi.png",stickerName];


    NSData *data = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:picURL]];
    if (data) {
        if ([data writeToURL:fileURL atomically:true]) {
            NSError *attachmentError = nil;
            UNNotificationAttachment *attachment = [UNNotificationAttachment attachmentWithIdentifier:fileName
                                                                                                  URL:fileURL
                                                                                              options:nil
                                                                                                error:&attachmentError];
            self.bestAttemptContent.attachments = [NSArray arrayWithObjects:attachment, nil];

        }else{
            NSLog(@"Data can't be written");
        }
    }

    [self contentComplete];

  }
 }
